I passed the end of that street 15-20 minutes before the bomb went off.
I was at home, almost falling asleep in my recliner after a long days work, when I felt the building shudder before the boom was heard and felt through the open windows here.
It is 10 minutes of slow walk from here to the bomb-site, I was thinking of going downtown to have a beer, but was too tired.
I have seen pictures from the work of Timothy McVeigh and other acts of terror or utterly mental confusion, but had hoped never to experience this so close, even if the warnings about such a development have been clear for a long time now.
It is really scary!
